MANUFACTURE OF LIN OLEUM.

No Drawing.

To all whom it may concern:

Be it known that we, Lorne E. BARTON, a resident of Niagara Falls, in the State of New York, and HENRY A..,GARDNER, residing in the city of Washington and District of Columbia, and being both citizens of the United States, have jointly invented certain new and useful'lmprovements in the Manufacture of Linoleum, of which the following is a specification.

Our present invention relates to linoleum products well known as composed principally of linoxyn, z. e. om'dized oils combined' with fabric, and employed as floor coverings, and its objects comprise imparting thereto, at less expense, and more edectively, certain desired properties; also certain novel properties, including, particularly, whiteness of coloration.

The procedures usually practised in the manufacture of linoleum products are already too well known for rehearsal here.

We attain our objects by incorporating with the linoleum product during its manufacture titanic material, for example, titanic oxid, or, preferably, titanic oxid in the form of minute particles adherent to particles of other materials, for example, the sulfate particles, hereinafter referred to.

It is important that-the titanic material shall be as ure, as amorphous, and as finely 1,196,031, dated August 29, 1916,

sub-divid as possible.

Therefore, we prefer to employ such titanic oxid concentrate roducts as are obtainable by such proce ures as described in Letters Patent Nos. 1,106,406, 1,106,407, 1,106,408, 1,106,409, 1,106,410, dated August 11, 1914, 'No. 1,166,547, dated January 4,

15 1916, and Nos. 1,196,029, 1,196,030, and

to Auguste J. Rossi and Louis E. arton; also, No. 1,189,229, dated July 4, 1916, No. 1,201,541, dated October 17, 1916, and Nos. 1,206,796, 1,206,797, and 1,206,798 dated December 5, 1916, granted to Louis Barton, or,-more particularly, do we, in some cases, prefer the composite titanic pigment products resulting from precipitation of minute titanic particles into coalescence with, and adherence to, particles of other matter, such last mentioned carrier pan Specification of Letters latent.

ticles consisting preferably of a sulfate base, or foundation, preferably calcium sulfate, precipitated in the same titanic sulfate solution as are the said titanic particles, and as is more fully described in Letters Patent granted to Louis E. Barton, No. 1,155,462, dated October 5, 1915, or No. 1,205,144, dated November 21,1916.

' The titanic material we admix with oil as by grinding, etc., in the manner usually practised in production of paints. The resultlng mixture is incorporated with the other constituents of the linoleum at any stage of the latters production. As regards inlay linoleum, for example, we add the titanic pigment either to the dried, ground, linoleum meal and grind them together preliminarily to the admixture and subsequent usually employed, or the titanic material may be added at the same time with these. As to rolled linoleum coverings, on the other. hand, we prefer to incorporate the titanic addition, as aforesaid, mixed with oil by spreading it upon the rolled linoleum sheets, in which case the respective materials mutually permeate and interlock with each other to an extent suficient to insure constant integrity of the final sheet product as a whole.

If other colorations than white are desired in the final products, we add such percentages as may be indicated of any appropriate tinting colors.

In whatever manner incorporated with the linoleum the titanic material, owing to its own very peculiar and characteristic ularly to the indices of refraction of the titanic compounds being greater than those of any other substances known to us as being heretofore comprised in the linoleum products referred to.

Having now described our invention, what we claim as new and desire to secure by Letters Patent is the following, viz:

1. Linoleum having therewith incorporated a titanic material.

2. Linoleum having therewith incorporated titanic oxid.

3. Linoleum having therewith incorporated particles of matter having thereto adherent titanic particles.

4:. Linoleum having therewith incorpomacaw rated particles of a sulfate base having thereto adherent titanic particles.

5. Linoleum having therewith incorpo-- rated particles of calcium sulfate having 20 thereto adherent particles of titanic oxid.
